A sbt plugin for walk on the dependency tree of Build to see if a specific task exists.
Use the Apache Pekko project as an example
add these line into project/plugin.sbt
addSbtPlugin("io.github.roiocam" % "sbt-depend-walker" % "latest")create PekkoDependWalker scala class on project/PekkoDependWalker.scala
